Help with a weapon Safety?

Im trying to have weapons require a safety function, script is below with attached Gyazo of the scripts location in the model.

http://gyazo.com/481b196c3c4e91e8d1ceb9a9a7d5d9bd

C = script.Parent.Parent.Safety
local p = script.Parent:GetChildren()

function Toggle()
	if C.Value == true then
		open()
	elseif C.Value == false then
		close()
	end		
end

function open()
	for i = 1, #p do
		if p[i]:FindFirstChild("Flangs") then 
			p[i].Flangs.Transparency = 0
		end
	end
end

function close()
	for i = 1, #p do
		if p[i]:FindFirstChild("Flangs") then 
			p[i].Flangs.Transparency = 1
		end
	end

end

C.Changed:connect(Toggle)

Put your Toggle function below the open and close functions ad see if that helps. As it stands now, it won't work due to order of operations in the script - the Toggle function has not visibility to your open and close functions unless they're placed before it.
